Sometimes "the catalog" fails us. And here's an example.
Brandon/Bruno2 is over getting engine parts ready for painting. And in the midst of that he asked me to figure out which of the three "dipsticks" is the right one for his engine, which is a 1982 351W from an F150. That should be easy 'cause they are marked. So, we read the markings: E2TE 6750-EA; E5UE 6750-DA; and E3TE 6750-CA.
Well, right off the bat we can toss out the E5UE as the "U" means it came from an E-Series van. But, to find the real one from the other two we went to 1994 version of the master parts catalog, which I have on CD:
Well, anyone spot either of those #'s in the right-most column? Nope?
Well, maybe Ford, in their infinite wisdom, changed the part number/identification number. So, we turned to the 1982 version of the master parts catalog, which I have on microfiche. Nope. Hmmm, what about the 1989 version? Bingo!
The moral of the story is that you have to have a wide variety of documentation in order to figure out these trucks. Ford added and deleted part and identification #'s from each issue of the master parts catalog. So sometimes you have to try several times in order to find what you are looking for.
